Zhigileva, O. N., Levykh, A. Y., Gorbacheva, E. V., 2020. Genetic polymorphism in populations of voles and shrews from the Kronotsky Reserve (Kamchatka Peninsula, Russia). Arxius de Miscel·lània Zoològica, 18: 75–83, Doi: https://doi.org/10.32800/amz.2020.18.0075 Abstract Genetic polymorphism in populations of voles and shrews from the Kronotsky Reserve (Kamchatka Peninsula, Russia). We studied genetic polymorphism of four mammal species Myodes rutilus, Myodes rufocanus, Sorex isodon, Sorex caecutiens from four localities, the Valley of Geysers, Uzon volcanic caldera, the Death Valley, and the Shore of Kuril Lake. In total, 172 individuals were genotyped using the inter–simple sequence repeat technique. We observed the lowest polymorphism in shrews S. caecutiens. In this species, 68.8 % of bands were polymorphic, and Nei's genetic diversity (h) was 0.27, while these values in S. isodon were 81.3 % and 0.29, respectively. Populations of M. rufocanus were the most polymorphic among the studied species (P = 91.4, h = 0.34). Polymorphism in M. rutilus from Kamchatka (P = 87.2, h = 0.29) was similar to that from Western Siberia. In addition, we found a high genetic differentiation of rodent populations. The interpopulation component of genetic variability was about 30–40 % (GST = 0.31 in M. rutilus and 0.39 in M. rufocanus). Gene flow among populations of M. rutilus from Kamchatka was two times lower than that of populations of the species from taiga ecosystems in Siberia.

Estudiamos el polimorfismo genético de cuatro especies de mamíferos Myodes rutilus, Myodes rufocanus, Sorex isodon y Sorex caecutiens de cuatro localidades: el valle de los Géiseres, la caldera volcánica Uzon, el valle de la Muerte y las orillas del lago Kuril. Genotipamos un total de 172 ejemplares utilizando la técnica de intersecuencias simples repetidas. Observamos el polimorfismo más bajo en la musaraña S. caecutiens. En esta especie, el 68,8 % de las bandas resultaron polimórficas y la diversidad genética de Nei (h) fue de 0,27, mientras que en S. isodon estos valores fueron de 81,3 % y 0,29, respectivamente. Las poblaciones de M. rufocanus fueron las más polimórficas entre las especies estudiadas (P = 91,4; h = 0,34). El polimorfismo de M. rutilus de Kamchatka (P = 87,2; h = 0,29) fue similar al de Siberia Occidental.
